ATOMIZING AND MIXING VALVE.

Specification of Letters Patent.

Patented Nov. 18, 1913.

To all whom it may concern:

Be it known that I, WILSON D. CRAIG WRIGHT, a citizen of the United States, re siding at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Atomizing and Mixing Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accom anying drawings, and to characters of reibrence marked thereon, which form a part of this specification.

The present invention has reference, generally, to improvements in delivery or atomizing valve-mechanism for introducmg fuel to the cylinder of an internal combustion engine.

The invention has for its principal object to provide a simple, efiective and clean delive or atomizing valve-mechanism for deli-vering and intermixing various fuel-elements comprising heavy hydrocarbons, including the natural crude mineral oils of paraflin or asphalt base, as well as kerosene and other manufactured or modified products of the same general-class, and air and water, to provide a fuel-mixture from the combustion of whieh 'power may be produced substantially after the method indicated in previously granted Letters-Patent No.832,728, dated October 9, 1906.

A further object of the present invention is to provide a valve-construction, for the purpose above indicated, which is subject to accurate mechanical control; which is adapted to thoroughly iutermix the fuel-elements; which is constructed to prevent leakage caused by back-pressure; and which is arranged to obviate chokin of its fuel-passages by the collection of dirt, or foreign elements.

Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of my present invention;

With the various objects of the present invention in view, the same consists, primarily, in the novel construction ofatomizingand mixing valve-mechanism for interna combustion engines heremaiter set forth; and, furthermoreythi! invention consists in the several novel arrangements and combinations of the various devices and parts, as well as in the details of the construction thereof, all of which will be hereinafter more fully described in the following specification and then finally embodied in the clauses of the claim which are appended to tion of the novel construction of atomizing and mixing valve-mechanism in its operative connection with the cylinder of an internal construction engine, the same being made according to and embodying the principles of the present invention Fig. 2 is a similar detail sectional view illustrating certain movable portions of the valve-mechanism in their open or operative position. Fig. 3 is a transverse section taken on line 3-3 in said Fig. 2, and looking in the direction of the arrow a:. Fig. 4 is another detail transverse section taken on line 44 in said Fig. 2, looking in the direction of the arrow y.

Similar characters of reference are em-' ployed in all of the herein-above described views, to indicate corresponding parts.

The novel atomizing and mixing valvemechanism comprising my present invention is designed to mix, atomize, and deliver to the engine-cylinder a hydrocarbon fuel comprising three elements, viz., a heavy hydrocarbon, water and air. The eneral theory of the inter-mixing or vaporizing of the said fuelvelements to roduoe a combustible fuel is described in ormer United States Letters-Patent No. 832,728 of October 9th, 1906, and consists in bringingtogether heavy hydrocarbon oil and water, the water taking the form of minute drops or lobules and the oil being carried on these rops or globules in the form of a very thin'film or coating, the air tending to further break up and atomize this union of oil and water, and also provide oxygen to the combustion of the gaseous mixture produced by such intermixmg of the fuel-elements, whereby, in this manner it is possible to use, in the production of a suitable gaseousfuel for bydrocarbon or internal combustion engines, a hydrocarbon of very low. or heavy grade, which without assistance would not be capable of the fine subdivision or atomizing of its mass by mixture with air alone, thus rendering, by the use of such'heavy or low gpade hydrocarbon, an exceedingly cheap el for power-production.

The novel construction of atomizing and mixing valve for combining to best advantage the three fuel-elements above-mentioned comprises, a tubular valve-body 1 provided with an exteriorly threaded extension 2, which is adapted to screw into a suitably threaded aperture in the walls 3 of the cylinder-chamber 4, and thus operatively connects said valve-mechanism with the engine- 0 linder. Said valve-body 1 and its extcn" sion 2 are provided with an inwardly extending tubular opening 5 which terminates at its outlet-end in a conical seat-portion 6 formed by the inclined walls at the terminus of said tubular opening, and communicating with said tubular opening is an outlet passage 7, the flared mouth 8 of which opens directly into the said cylinder-chamber 4. Said tubular opening 5 is open at the outer end of said valve-body 1 so as to receive a movable valve-member 9 which penetrates into and is slidably arranged within said tubular opening. Said movable valve-body 9 is provided at its inner endwith a conical head 10 which is adapted to be received upon said conical seat-portion 6, when the valve'mechanism is in its closed position. The outer end of said valve-body 1 is provided with a receiving socket or chamber 11 of greater diameter than the diameter of said movable valve-member 9, so that a suitable packing material 12 may be packed around said movable valve-member 9 to prevent leakage of the fuel-elements at the point of entrance of said movable valvemember into said valve-body. Said receiving socket or chamber 11 is interiorly threaded so that a suitable gland 13 may be screwed home to hold said packing material properly in place. The outwardly projecting end of said movable valve-mem er 9 is provided with a flanged collar 14, secured thereto in any suitable manner. Extendin outwardly from said valve-bodyl, and pre erably forming an integral part thereof, is a bracket-arm 15 terminating in perforated ears 16 which support the fulcrum-pin 17 of a bell-crank lever 18 mounted upon the latter. The upwardly extending arm of said bell-crank lever 18 terminates in a forked ortion 19 which straddles said flanged collitr 14, and the free ends 20 of which are in operative engagement with said flanges of .said flanged collar. Connected with the other arm of said bell-crank lever 18, by means of a forked connecting piece 21, is a connecting rod 22. The vertical movements of said connecting rod, which may be enforced by any well-known cam-movement operated and timed in connection with the 'gitudinal crankshaft of the engine, operates said bellcrank lever 18 to produce the reciprocating or sliding movements of said movable valvemember 9 within said valve-body 1 to cause the properly timed opening and closing movements of the valve-mechanism, governed in accordance with the movement of the piston 23 within the cylinder-chamber 4, as will be readily understood. Said mov-- able valve-member 9 is provided with a longroove or channel a which is engaged by a key or spline B secured in the said valve-body 1, thus permitting the longitudinal sliding movement of said valvemember, but preventing any twisting or turning of the same on its longitudinal axis, so that its proper related position with the said valve-body is always maintained. The said movable valve-member 9 is provided with a tubular passage or duct 24 which extends longitudinall and inwardly from its inner end to a suita le distance, said passage or duct 24 being closed by a suitable plug or closer 25. The said passage or duct 24 provides a mixin chamber for the reception of the several uel-elements. Extending inwardly from the outer surfaces of said conical head 10 of said valve-member 9 are a plurality of radiating spray-ducts 26 which communicate with said assage or duct 24. When said conical head 10 of said valvemember 9 is normally seated upon said conical seat 6, viz., when the valve-member 9 is in its closed position, the outlet mouths of said spray-ducts 26 are closed by the contact with said conical seat 6. Connecting with the inner end of said passage or duct 24 are a series of radiating inlet-passages, namely, a hydrocarbon passage 27, a water passage 27' and an air passage 27 all of which extend outwardly to the outer surface of said movable valve-member 9. Said valve-body 1 is also provided with a series of radiating extensions or bosses 28 each being provided with an intake-passage, one having a hydrocarbon intake-passage 29, another a Water intake-passage 29', and another an air intake-passage 29". The outer ends of said intake-passages are interiorly threaded for. the reception of suitable delivery pipes 30, 30' and 30". adapted to convey the several fuel-elements to said intake passages.

The novel valve mechanism, thus above described in detail, operates as followsz-At proper times through the operation of the bellcrank lever 18 upon the movable valvemember 9, in the manner above indicated, said valve-member 9 is drawn outwardly until its several inlet passages 2'1, 27 and 27 register respectively with the intake passages 29, 29 and 29" of the valve body 1, and this movement also unseats the conical head 10 from the conical seat 6, and thus opens the spray ducts 26, in the manner indicated in Fig. 2 of the accompanying drawings. This operation of the movable valvemember 9 thus opens the valve mechanism and prepares the Same for receiving, mixing and atomizing and consequently delivering the proper fuel charge to the cylinder chamber 4. The several fuel elements are now impelled by suitable pumping mechanism through their respective delivery pipes 30, 30 and 30 into the intake passages of the valve-body 1 and through the inlet passages of the movable valve member 9 into the mixing chamber formed by the passage or duct 24. The impelled streams of h drocarbon, water and air passing through t eir respective passages and into the mixing chamber of the movable valve-member impinge upon each other and are thoroughly intermixed together, and in such intermixed condition are expelled from said mixing chamber with atomizing effect through said spray ducts 26, the direction of which causes the atomized streams to again impinge upon the inclined surface of said conical seat 6 from which they rebound in more thoroughl subdivided particles or oil coated globu es of water, finally being expelled through the outlet passage 7 into the cylinder chamber 4, where the mixture thus delivered after being compressed by the rising piston 23, comes in contact with the hot tube 31 communicating with the cylinder chamber 4, and is thereupon exploded, driving downwardly the piston 23 to produce its power stroke. In the meantime a reversedmovement of the bellcrank lever 18 has returned the movable valve-member 9 to its normal initial position, thus closing the valve-mechanism against the entrance of the fuel elements, and shutting off the delivery openings thereof.

The extreme simplicity, both of construction and operation-"of the novel mixing and 'atomizinglvalveabove described, will be apparent, t e'moving parts are greatly simplified in construction, and the chance of disarrangement considerably minimized, at the same time the directness of its fuel passages, and the positiveness of its cut-off when in closed position, renders the mechanism little liable to chokage through the collection of dirt or foreign particles carried in the fuel elements, or otherwise caused.

I am aware that changes may be made in the various arrangements and combinations of the several devices and parts and in the features of my present invention without dearting from the scope thereof, as described in the foregoing specification, and as defined in the claims appended thereto.
